SLE10 Expert Series Slot Sensor Overview
The SLE10 Series Slot Sensor (sometimes called a “Fork Sensor”)
comprises an opposed-mode emitter and its receiver inside a single
convenient housing. Opposed-mode sensing is very reliable, and the
single self-contained housing provides easy installation, with no
sensor alignment required. In addition, the molded-in arrow on the
emitter portion of the housing and the slotted design on the receiver
portion of the housing show at a glance the position of the beam,
simplifying installation placement.
Expert series sensors feature easy-to-use push-button programming,
performed in TEACH mode. TEACH-mode programming may be
performed using either the push button, or remotely, using a remote
switch or process controller. The programming determines whether
the sensor outputs will conduct in light or dark conditions, and defines
the light and dark conditions for the sensor in each application. The
remote switch also may be used to disable the programming push
button for security.
The Dynamic TEACH option provides a means for teaching a series of
conditions; the SLE10 monitors the sensing events and automatically
sets the threshold between light and dark conditions.

Using the SLE10 Expert Series Slot Sensor
RUN Mode
Normal operation of the SLE10 Expert is called RUN mode. The two LED indicators
(bi-color Green/Red and Yellow) operate as follows in RUN Mode:
Green (RUN Mode): ON steady whenever power is applied
Flashes as received light level approaches the switching threshold
(stability indicator. The stability indicator signals when
maintenance or reprogramming is needed during RUN mode.)
Yellow (Output): ON when the outputs are energized (conducting)
OFF when the outputs are de-energized (not conducting)
If contrast is marginal, the bi-color indicator will flash green (to indicate instability).
Reprogramming the sensor, or cleaning the sensor lenses may solve a problem with
stability.
TEACH Mode
Programming of the SLE10 Expert – setting the sensitivity and selecting output ON and
OFF conditions – is performed in TEACH Mode. The SLE10 provides two methods for
programming: Static TEACH and Dynamic TEACH. Static TEACH is used in all
programming situations to set up the sensor’s output ON and output OFF conditions.
Sensitivity is then set using either the Static method described below or the Dynamic
method on page 4.
Both Static TEACH and Dynamic TEACH may be performed using either the sensor’s
TEACH push button or the Remote TEACH line (see page 6).
Static TEACH
Determining the Output ON and OFF Conditions
The two sensing conditions may be presented in either order. The condition presented
first is the condition for which the outputs will energize (the “Output ON” target).
Setting Sensitivity
Sensitivity is automatically set (and optimized) when teaching the sensor the ON and
OFF conditions. When the push button is clicked, the sensor samples each sensing
condition and registers it into memory. After the second sensing condition is
registered, the SLE10 Expert automatically sets the sensitivity to the optimum value
for the application, and then returns to RUN mode.
The two LED indicators (bi-color Green/Red and Yellow) operate as follows in
TEACH Mode:
Red (TEACH Mode): Lights when the sensor “sees” its modulated light source;
pulse rate is proportional to the received light signal strength
during TEACH programming
Yellow (Output): ON to indicate TEACH output ON condition
OFF to indicate TEACH output OFF condition
The Signal Strength indicator is Banner’s exclusive AID™(Alignment Indicating
Device). Its pulse rate increases as the received light signal strength increases (during
programming). This feature simplifies accurate alignment during TEACH mode, and
gives a relative indication of sensing contrast between the light and dark conditions.

A Note About the “Clicks”: Clicks are meant to be pressed firmly, then quickly
released. Indicators go ON or OFF after a brief delay; do not wait until LEDs change
status before releasing push button. (If push button is pressed for 2 seconds or
longer, sensor will automatically return to RUN mode.)
Dynamic TEACH
Dynamic TEACH is a method of setting the sensor’s sensitivity while the object to be
sensed is in motion. Typical applications are label sensing and small parts detection. In
a label application, web flutter may change the amount of light passing through the
label and its backing material. Dynamic TEACH will sense this variation and adjust the
sensitivity to account for it.
In a small parts detection application, alignment of the object to the sensor’s effective
beam may make Static TEACH difficult. In this case, Dynamic TEACH will allow you to
pass individual or multiple parts through the beam; the sensor then will detect them and
set the sensitivity automatically.
Determining the Output ON and OFF Conditions
Dynamic TEACH is used for optimizing the sensor’s sensitivity and will not configure the
output ON and OFF conditions. A Static TEACH must be used first to change the output
ON and OFF conditions, if needed. If the outputs are configured properly for your
installation, Dynamic TEACH may be performed as needed without reverting back to
Static TEACH.
Setting Sensitivity
Sensitivity is automatically set and optimized when the sensor is taught dynamically.
When the push button is depressed and held, the sensor continues to sample events
and registers them into memory. Upon release of the button, the sensor chooses the
optimum setting for the application and then returns to RUN mode.
Push Button Resulting Indicator Status
TEACH Condition #1
(Output ON state)
Present the first
sensing condition to
the sensor and singleclick.
†
Press and hold until
the bi-color (green/red)
indicator begins to
flash red, or turns OFF.
Yellow: ON
Red: Pulses to indicate relative received signal
strength.
Yellow: OFF
Red: Pulses to indicate relative received signal
strength.
TEACH Condition #2
(Output OFF state)
Present the second
sensing condition to
the sensor and singleclick.
If contrast is acceptable, the sensor returns to
RUN mode; other wise it will return to TEACH
Condition #1.
Green: ON (or flashes if signal is close to the
switching threshold).
Yellow: OFF, until the sensing condition changes.
†
NOTE: The sensor will return to RUN mode if the first TEACH condition is not registered within 90 seconds. TEACH mode may be cancelled
before either condition #1 or #2 by holding the push button depressed for ≥ 2 seconds.
